S. palmifolium is worth persisting with, I believe that there are various forms, with a lot of variation in plant size. S macrocarpum in a good form is a lovely plant, much better than the S patagonicum which I once grew but have only a hazy memory of. S striatum tends to be short lived here too, but seedlings turn up in cultivaded soil and a large stand of it can be very impressive. It doesn't like dank winters and the leaves turn black one by one- I think this may be fungal?
